TL;DR: In this article, the authors synthesize current research relating atmospheric N deposition to effects on terrestrial and freshwater ecosystems in the United States, and to estimate associated empirical N critical loads, defined as the input of a pollutant below which no detrimental ecological effects occur over the long-term according to present knowledge.

TL;DR: In this paper, the authors synthesize current research relating atmospheric nitrogen (N) deposition to effects on terrestrial and aquatic ecosystems in the United States and identify empirical critical loads for atmospheric N deposition.

TL;DR: The Tree Chemistry Database is a relational database of C, N, P, K, Ca, Mg, Mn, and Al concentrations in bole bark, bole wood, branches, twigs, and foliage containing reported nutrient and biomass values for tree species in the Northeastern United States.

TL;DR: In this paper, the authors used multiple chemical criteria to calculate critical loads for S and N deposition (CL (S+N)) and used the Very Simple Dynamic (VSD) model to predict the effects of deposition reduction scenarios on critical thresholds for four forested sites in GSMNP.

TL;DR: In this paper, the authors determined optimal ranges of topographic (elevation, aspect, slope gradient), climatic (average temperature for January, July, and May to September; annual and May-to-September precipitation), and soil (pH, percent clay, percent coarse sand, permeability, depth to bedrock) parameters for 23 tree species of the northeastern United States.
